摘要
We investigated by attenuated total reflection Fourier infrared spectroscopy the chemical behavior of macromolecules on the surface of polyurethane microporous film doped with silver nanoparticles at temperatures between 25 and 200 degrees C. Silver nanoparticles interact with the urethane group and form a urethane-silver-urethane structure with a specific surface configuration and a higher resistance to temperature. Chemical transformations of the macromolecules on the surface of polyurethane film depend on both the silver nanoparticles concentration and temperature.
